SHEET-GLASS MACHI N E.

SPECIFICATION Af ro'rmng 'part of Letters Patent No. 754,752, datedMarch 15, 1904.

Application i'iled March Z5, 1903.

To MZ whom it may concern:

Be itlrnown that I, SAMUEL DEELEY, of Converse, county of Miami, andState of Indiana, have invented a certain new and useful Sheet- GlassMachine; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, in which like numerals refer to like parts.

The object of this invention is the construction of a practicalapparatus for the fanufacture of sheet-glass for window-glass and thelike without blowing and by mechanical means.

The chief novel feature of this invention consists in combining two setsof rolls through which plastic glass may be passed to form a sheet witha reciprocating conveyer to receive said sheet and a leer, between themouth of which and the rolls the conveyer reciprocates for receiving asheet of glass as it comes from the rolls and transferring it to themouth of the leer. This idea is carried further by providing two sets ofrolls and two leers with a single conveyer reciprocating between them,so that the rolls may be alternately used and the conveyer betransferring the sheet of glass, while moving in either direction.

In addition to the foregoing features of invention are the improvementsin details of construction, all of which will appear from theaccompanying drawings and the following description and claims.

In the drawings, Figure 1 is a front elevation of the central portion ofthe apparatus. Fig. 2 is a horizontal section of a portion of theapparatus, parts being shown in plan. Fig. 3 is a detail plan View of 'aportion of the means for operating the conveyer. Fig. i is a verticallongitudinal'section near the center.

fbe of any desired length or construction; but

The

Serial No. 149,594. (No model.)

Referring to the construction shown, I proi vide two leers 10, parallelwith each other and separated somewhat, substantially as shown. There isnothing new or peculiar about these leers, and my invention will beunderstood without explaining the details of their construction. What Icall a kiln 11 is constructedat a right angle to said leers, extendingpast one end of the leers to a point about equidistant on each side andconnected with said leers, so that there is an opening from This kilnmay as shown its top is divided into sections. section 12- is midwaybetween the ends of the leers, while the sections 13 are at the ends ofthe leers and register therewith. The other sections 14. eXtend to theright and left of the central section mentioned. The sections 13 and 111are adjacent each other, while the section 12 is separated somewhat fromthe sections 13 and leave a space for aset of rolls on each side of saidcentral section 12. These rolls consist, in whatis herein shown, ofthree series of rolls 15, 16, and, 17. They are hori- Zontally mountedin pairs, the rolls of each pair being mounted in the same horizontalplane and their peripheries bearing against each other. The diameters ofthe three series of rolls are graduated, the larger rolls being placedabove and immediately under them the medium rolls 16 and immediatelyunder the latter the small rolls 17. The contacting points of thedifferent pairs of rolls are therefore in the same vertical line, sothat the molten glass 18 deposited on the upper pair of rolls 15 willpass down between said rolls in a sheet that will proceed downwardbetween the rolls 16 and the rolls 17 until it reaches the stone 19 onthe moving conveyer 20,

as shown in Fig. 7. Said rolls are mounted in stands 21, secured on cachside of the kiln and facing each other. The shafts 22 of the rolls havetheir bearings in a pair of bearing-blocks 23, whose adjacent faces areprovided with semicircular bearinggrooves that register with each other.Said blocks are provided with dovetailed extensions 24, as seen in Fig.9, that fit in corresponding laterally-extending grooves in the stands21, so as to be laterally movable, as shown in Fig. 6. On the upper pairof rolls a pair of triangular end plates 26, connected by the bars27,loosely rest, there being one at each end of a pair of rolls to preventthe glass from flowing over the ends of the rolls. Under each set ofrolls there are 4fire-boxes 28, extending from one side wall to theother of the kiln 11 and provided with openings 29, through whichgaspipes ay be inserted for warming the rolls at the beginning of theoperation of the apparatus. I also place sawdust in said lireboxes andset it on fire for smoking the rolls. After the rolls are initiallyheated and the operation of the device begun the hot glass will keepthem at the proper temperature.

In the kiln I show a conveyer consisting of anumber of carriages 20,connected by couplings 30. Said carriages have a top portion forsupporting the stone 19 and a frame 31,

carried on wheels 32, said wheels being adapted to move on the rails 33of a track extending centrally and longitudinally of said kiln andformed of the rails 33 and the cross-ties 34. The width of thesecarriages is somewhat less than the sections of the kiln, and

their tops move just below the sets of rolls and close to and at thesame level as the openings 35 into the leers, so that glass can bereadily moved by a workman from the conveyer into the leer.

The conveyer is moved by a cable 36, which is connected at each end tothe respective ends of the series of carriages and passes over a pair ofpulleys 37 and 38, the latter shown in dotted lines and mounted in thestands 39 at each end of the kiln, so that said cable extends beneaththe track on which the conveyer-carriages move. A trough 40 is placedbeneath the track in which said cable may move, as appears in Figs. 3and 4. About midway of the kiln a pair of horizontal pulleys 41 aremounted in the timbers 42, against which a cable 36 moves in passingaround its driving-drum 43, and by this means the cable is moved iirstin one direction and then in the other, so as to reciprocate theconveyer from `one end of the kiln to the other.

The cable-driving drum 43 is secured to a vertical spindle 64, fittingloosely on the lower end of the shaft 44. Said shaft is mountedvertically in the bearings 45 and near its lower end carries thebevel-gear 66, that is driven constantly by the bevel-gear 47 on thehorizontal shaft 48, mounted in the bearings 49 and driven by a pulley50 from any suitable source of power.

The rolls are driven by a series of bevelgears 51 on the vertical shaft44, that mesh on each side with the bevel-gears 52, secured onoppositely-extending shafts 53, mounted in the bearings 54 and carryingworms 153. There is one pair of these worms for each pair of rolls, andthose on each shaft mesh with a pair of oppositely-cut worm-gears 55,secured on the shafts 22 of the rolls, whereby the rolls of each pairwill be driven in opposite directions.

The spindle 64 has loosely mounted on it the bevel-gear 46, so that saidgear may be vertically slidable by means of the lever 57 to move it intoor out of engagement with the bevel-gear 47. A key 70 is secured to saidspindle 64, that fits loosely in a groove in the gear 46, so the latteris vertically movable on the spindle 64, so that'when said gear 46 iselevated it, will be actuated by the gear 47 in a direction opposite tothe gear 66and will rotate the drum in a reverse direction; but when thegear 46 is in its lower position it will disengage the gear 47. There isa clutch 7I, slidably mounted on the shaft 44 by a key 72, that engagesthe upper end of the spindle 64 and actuates it when it is depressed bythe lever 56, and thereby rotates the drum, but does not do so when theclutch is elevated by the lever 56 out of engagement with the spindle64. In other words, this construction is such that the shaft 44 rotatesconstantly and drives the rolls always in the same direction, whereasthe drum rotates alternately in one direction or the other forreciprocating the conveyer. When the clutch 71 and the gear 46 arelowered, the shaft 44 will drive the conveyer in one direction, and whenthey are elevated the gear 46 and spindle 64 will drive the conveyer inthe opposite direction. When the clutch 71 is elevated and the gear 46is lowered, leaving the levers 56 and 57 toward each other, the conveyerwill be stopped. This part of the mechanism may be of any suitablearrangement familiar to mechanics, as it constitutes no part of theinvention, and I do not wish to be limited to what is herein shown.There are openings 58 through the side of the kilnopposite the leers,whereby the operator can readily transfer the sheets of glass from theconveyer into the mouths of the leers. Openings 59 are provided in thecentral section 12 for inserting the means for flattening the glass. Thegearing is such that the movement of the con veyer and of theperipheries of the rolls will be at the same speed.

Behind the kiln there isa gas-pipe 60 with nozzles 61 extending from itinto the kiln at each section and having valves 62 for regulating thesupply of gas, so as to control the temperature of the kiln and thevarious parts thereof.

IOO

IIO

In the operation of the double apparatus which I here show a man standsbeside the kiln in front of the mouth of a leer for removing the glassfrom the conveyer into the leers as the conveyer-carriages pass themouth of the leers. Another man stands in front of the openings 59 ofthe central section 12 between the two sets of rolls for flattening theglass on'the stones. While the conveyer is moving in one direction-sayto the rightglass is introduced only through the left set of rolls, andwhile the conveyer is moving in the opposite direction glass isintroduced only through the right set of rolls. When the conveyer ismoving to the left, as shown in Fig. 4, glass is being supplied to theconveyer through the right set of rolls, and as the glass comes downfrom between the rolls, as shown in Fig. 7, the conveyer moves to theleftwith the same speed as the sheet of glass moves down, so that theglass will not be drawn or' jammed, but will move off to the left on thestone on the conveyer and lie flat thereon unharmed by the movement ofthe conveyer. To accomplish this result, it is necessary to have asingle or common means for driving both the conveyer and the rolls,whereby the same speed will always be maintained, for any differentspeed would cause the sheets of glass to be injured or destroyed by theconveyer. As the foremost conveyer with the first sheet of glass movesto the left through the middle section 12 of the kiln the attenerflattens the sheet of glass and smooths it out in the usual way and byany usual means. While he is doing that another sheet of glass is comingdown through the rolls on the iiattening-conveyer, and as that secondsheet of glass comes to him he flattens it in the same way. As theconveyer moves farther the carriage carrying the first sheet of glasswill come opposite the mouth 35 of the left-hand leer, and the workmanstanding at that point removes said sheet of glass from the conveyerinto the leer. He continues to do this with the subsequent sheets ofglass until the conveyer has reached its limit of movement or passed inits movement in a direction to the left. Then the movement of theconveyeris reversed,and the workman whose duty it is to remove theglassfrom the conveyer to the leers changes his position to theright-hand leer, and therefore the glass is introduced into theleft-hand set of rolls, and as the glass comes to the flattener and tothe right leer it is treated in the same manner as above described.

In the operation of this apparatus the chief function of the kiln 1l isto furnish room for the operation of the conveyer-carriages and keepthem properly heated. The annealing is done by the leers. No means forconveying the molten glass to the sets of rolls has been shown,.as itconstitutes no necessary part of this invention. It may be done by atrolley-like apparatus extending from the pot to a point above the rollsor by any other means heretofore used forsubstantially similar purposes. Each charge of glass should preferably be sufficient to form oneplate of glass. The function of the rolls of each set is to convert theirregular mass of molten glass into sheet form. The upper and largerpair of rolls are preferably not set quite so close together as thelower rolls, and they convert the body of glass into a sheet, but do notleave the sheet smooth. The function of the lower rolls 16 and 17 is tofurther smooth and remove the wrinkles and irregularities in the.

surface from the sheet of glass and to give to it its final thickness.

What I claim as my invention, and desire to secure by Letters Patent, is
